I have a 1990 superjet that i took to the ocean, my flush hose wasnt flushing the engine well, but thought it was good enough, a couple weeks later i took it to a river and moments into my ride the motor mounts broke. I havnt touched it in a couple of years and now i want to bring it back to life, but my main qurstion is, did the salt water ruin my engine after sitting so long without a proper cleaning
